X-RAY APPARATUS, IMAGE PROCESSING DISPLAY APPARATUS AND COMPUTER PROGRAM PRODUCT
First Claim
1. An X-ray imaging apparatus comprising:
- an X-ray image taking unit that takes an X-ray image by irradiating an X-ray to a subject and detecting the X-ray passed through the subject;
a three-dimensional blood-vessel information creating unit that creates information concerning positions of a three-dimensional blood-vessel core line and a blood-vessel lesion-site inside a blood vessel to be imaged, based on three-dimensional volume data obtained from an image taken by a medical diagnostic imaging apparatus;
a blood-vessel lesion-site-depth information image creating unit that creates a blood-vessel lesion-site-depth information image in which a display pattern of a blood-vessel lesion-site is changed in accordance with whether the blood-vessel lesion-site is present in front of or in the back of a three-dimensional blood-vessel core line, based on the information concerning positions of the three-dimensional blood-vessel core line and the blood-vessel lesion-site created by the three-dimensional blood-vessel-information creating unit; and
an X-ray image display unit that displays the blood-vessel lesion-site-depth information image created by the blood-vessel lesion-site-depth information image creating unit in a superimposed manner over the X-ray image.

Abstract
An X-ray imaging machine is configured such that a three-dimensional blood-vessel information creating unit creates information concerning a three-dimensional blood-vessel core line and a position of a plaque in a subject blood vessel based on three-dimensional volume data obtained from an image taken by an X-ray computed tomography apparatus. A plaque-depth information image creating unit creates a plaque-depth information image on which the plaque is differently displayed in accordance with whether the plaque is present in front of or in the back of the three-dimensional blood-vessel core line with respect to a projection direction, based on the created information concerning the three-dimensional blood-vessel core line and the position of the plaque. An X-ray image display unit displays the created plaque-depth information image over an X-ray image in a superimposed manner.
